特厚煤层采煤方法选择分析

Selection and Analysis of Mining Method in Extra-thick Coal Seams

采煤方法作为矿井生产作业开展的核心要素,确保对其选择的科学、合理对整个矿井生产的高效、安全开展意义重大。以此为出发点,针对特厚煤层采煤方法的选择开展探究。结合具体工程实际,分别对综放开采工艺和大采高分层开采工艺在A矿2#煤层回采中的适用性做出分析,并通过两者间的对比,确定A矿2#煤层回采更适宜选用综放开采工艺,希望能为其他矿井相似工程的开展提供参考。

As the core element of mine production,mining method is of great significance to ensure the scientific and reasonable selection of mining method for the efficient and safe development of the whole mine production.Taking this as a starting point,the selection of mining methods for extra-thick coal seams was explored.Combining with specific engineering practice,this paper made an analysis of the applicability of fully mechanized caving mining technology and large mining height slicing mining technology in No.2 coal seam mining of A Mine,and through the comparison between them,determined that fully mechanized caving mining technology was more suitable for No.2 coal seam mining of A Mine,hoping to provide reference for similar projects of other mines.
